Premiere Pro CC 2014 Crashing with rendering, freezing system, and more

Question

Hello,
I'm having some serious issues with Premiere pro on my late 2013 iMac.
OSX 10.9.5
3.2GHz Intel Core i5
16GB 1600 MHz DDR3
NVIDIA FeForce GT 755M  1024MB
I'm working in 1920x1080 23.976fps. Media files are from sony FS700 .MTS and Cannon 5DmkIII .mov
Multiple times per day, PP crashes on me. It all started when I was getting really choppy playback which would be accompanied by this error message:
A Low Level Exception has occurred in ImporterMPEG (Importer)
This would soon after lead to the program freezing and me having to force quit the program. After contacting Adobe the first time about this persistent issue, the tech explained to me that it was a "Memory Leak" issue and that there was nothing that could be done. After the support team member ended our chat online before helping me solve my issue, I called support. I provided my case number and this person picked up where the helplessly left me and did the typical Adobe one fix all: He went into the hidden library and cleared all of my preferences, removed any third party plugins, and cleared the files in the root applications Adobe folder, renamed a folder "Adobe.Old" etc.
As I explained to the support team member on the phone, this is not a solution but rather a bandaid until it happens again.
Low and behold it has happened again. This time the support team member had me create a new System Administrator account on my computer thinking that there was a permissions problem with my other account which was conflicting with PPCC2014. While this was a major pain to switch between the new account and any other program that I had set up for day to day work, it allowed me to continue editing and at least (at a less efficient rate) get things done.
Now, while using my new System Administrator account, I am getting terrible crashes that not only stall the program, but force me to hard re-boot my computer. These crashes are accompanied by a terrifying looking screen that I was only able to capture once.
They've only become more intimidating as now I cant even see the program when this happens, but this is the only screen capture that did not turn out completely black.
I'm looking to see if anyone has had any extreme issues like this and if so how they were able to fix it. I've now spent 6+ hours with support and after the last one was told I would receive a personal email follow up by the end of the day (never happened) to take further actions based on the performance after the new account creation.
I need help. Now.

Hi John,
First of all, try this: Re: A low level exception occured in: Importer MPEG (Importer)
Next, make sure that if you updated OS X to 10.9.x, or later, you must check the following each time you update: Premiere Pro CC, CC 2014, or 2014.1 freezing on startup or crashing while working (Mac OS X 10.9, and later)
Other things to try:
Sign out from Creative Cloud, restart Premiere Pro, then sign in
Update any GPU drivers
Trash preferences
Delete media cache
Remove plug-ins
Repair permissions
Disconnect any third party hardware
Remove QT components from Mac HD > Library > QuickTime
If you have a CUDA GPU, ensure that the Mercury Playback Engine is set to CUDA, not OpenCL
Disable App Nap
Reboot
Report back if anything here worked for you.
Thanks,
Kevin
